Customizing Your Arby's Order for a Low-Carb Diet
Staying on a low-carb diet while eating out can be challenging, but fast-food restaurants like Arby's offer surprising flexibility if you know how to order. The simplest and most effective strategy is to customize your order by removing the high-carb bun and replacing it with a salad or simply eating it as a protein-rich bowl. The iconic Classic Roast Beef, when deconstructed, serves as the foundation for a genuinely keto-friendly meal.
The Classic Roast Beef: The Ultimate Low-Carb Choice
When ordered 'no bun,' the Classic Roast Beef is the clear winner for anyone seeking the lowest carb sandwich at Arby's. The core ingredients—the famous slow-roasted beef—are naturally low in carbohydrates. This provides a high-protein, satisfying base that can be enjoyed with your choice of low-carb sauces or cheeses. Simply ask for your roast beef in a bowl or in a lettuce wrap to keep the carb count minimal. The Junior Roast Beef slider is another excellent choice, as its smaller portion of meat also makes for a great low-carb base once the bun is removed.
Other Low-Carb Arby's Menu Hacks
While the Roast Beef is the star, other menu items can also be modified to fit a low-carb lifestyle. For example, the Beef 'n Cheddar, with its creamy cheese sauce, can be made low-carb by forgoing the bun and red ranch sauce. The cheese sauce itself adds a few grams of carbs, but it's a worthwhile trade-off for many. For those who prefer other meats, the Roast Turkey and Corned Beef options can also be enjoyed without the bread. However, be mindful of sauces, as many contain hidden sugars that can increase your overall carb intake. For instance, the Red Ranch sauce is best avoided on a keto diet.
Navigating Condiments and Add-ons
Condiments are a critical consideration for a low-carb meal. Some Arby's sauces are higher in sugar than you might expect, while others are relatively safe. Stick to mustard or request sides of Horsey Sauce sparingly, as these can add some carbs. Plain, yellow mustard is generally a safe bet. Toppings like sliced cheese (provolone, Swiss) or bacon are excellent additions that increase fat and protein without adding significant carbs. Ordering extra shredded lettuce can also add volume and a fresh crunch to your meal.

Building a Complete Low-Carb Meal
To make your bunless sandwich a complete meal, consider pairing it with a side salad (with a low-carb dressing like ranch, or simply olive oil and vinegar if available). While Arby's famously features curly fries, they are a definite no-go for a low-carb diet. Stick to water, unsweetened iced tea, or a diet soda for your beverage.
